摘要：

An overview is given of what we know about the frequency of kinematically decoupled cores in dwarf elliptical galaxies. New observations show that kinematically decoupled cores happen just as often in dwarf elliptical as in ordinary early-type galaxies. This has important consequences for the formation of kinematically decoupled cores. Our currently most popular theory for kinematically decoupled cores in dwarf ellipticals is that they were formed in a poor group environment or in isolation, and subsequent fell into the cluster environment where star formation was quenched.
